Rotary screw air compressors work by trapping air between two meshed rotors and reducing the volume of that trapped air as it moves down through the rotors. This decrease in volume results in compressed air, which can be used to power pneumatic air tools, inflate tires and perform many other applications. .
Stellar Truck Mounted Rotary Screw Air Compressors boast many hardworking, long-wearing features: 1. Precision-engineered, rotary screw air-end is oil-injected to eliminate metal-to-metal contact of the two compressor screw lobes for continuous 100%. .
The advantages of rotary screw mobile air compressors over other types of compressors that can be mounted on service vehicles include: 1. Continuous airflow/100% duty.

A down-the-hole drill, usually called DTH by most professionals, is basically a jackhammer screwed on the bottom of a drill string. The fast hammer action breaks hard rock into small cuttings and dust that are evacuated by a fluid (air, water or drilling mud). The DTH hammer is one of the fastest ways to drill. .
DTH is short for “down-the-hole”. Since the DTH method was originally developed to drill large-diameter holes downwards in surface-drilling. .
A is first thought to have been used for rock drilling in 1844. Many quarries used hand held tools that required the driller to suspend himself from a rope over the. .
In DTH drilling, the percussion mechanism – commonly called the hammer – is located directly above the drill bit. The drill pipes transmit the necessary feed force and rotation to the hammer and the bit, along with the fluid (air, water or drilling mud) used to. .
DTH products can be used in the following applications:• Mining- drill and blast holes in open pit mining, where the drill operator will drill several holes, then.
